Hope for more accurate diagnosis of memory problems
Wed, 30 Jul 2014 09:40:47 EDT - More accurate tests could be created to diagnose diseases such as Alzheimer's or memory problems stemming from head injuries, leading to earlier intervention, according to new findings from researchers. The research involved investigating the components of memory using a combination of tests and neuroimaging -- a method that could be used to create a diagnostic tool for distinguishing between different types of dementia, memory damage from stroke or forms of amnesia caused by head trauma.
Ablation Increases Survival for Adults with Atrial Fibrillation
Wed, 30 Jul 2014 09:35:22 EDT - Easing heart palpitations is one benefit of catheter ablation. A longer life span is another. Study shows 60 drop in cardiovascular mortality after ablation for atrial fibrillation. More than 4 million people have atrial fibrillation, an age-related heart rhythm disorder that can cause a fluttering sensation in the chest and impair the heart's ability to pump blood.
Fossils found in Siberia suggest all dinosaurs could have been feathered
Wed, 30 Jul 2014 05:05:16 EDT - The first ever example of a plant-eating dinosaur with feathers and scales has been discovered in Russia. Previously only flesh-eating dinosaurs were known to have had feathers, so this new find raises the possibility that all dinosaurs could have been feathered.
Acupuncture provides significant quality of life improvements among breast cancer patients taking drugs to prevent recurrence, study shows
Wed, 30 Jul 2014 04:34:04 EDT - Use of electroacupuncture (EA) – a form of acupuncture where a small electric current is passed between pairs of acupuncture needles – produces significant improvements in fatigue, anxiety and depression in as little as eight weeks for early stage breast cancer patients experiencing joint pain related to the use of aromatase inhibitors (AIs) to treat breast cancer. The study is the first demonstration of EA’s efficacy for both joint pain relief, as well as these other common symptoms.
A blood test for suicide risk? Alterations to a single gene could predict risk of suicide attempt
Wed, 30 Jul 2014 04:34:02 EDT - Researchers say they have discovered a chemical alteration in a single human gene linked to stress reactions that, if confirmed in larger studies, could give doctors a simple blood test to reliably predict a person’s risk of attempting suicide.
Revolutionary microshutter technology hurdles significant challenges
Tue, 29 Jul 2014 22:56:12 EDT - NASA technologists have hurdled a number of significant technological challenges in their quest to improve an already revolutionary observing technology originally created for the James Webb Space Telescope.
NASA-funded X-ray instrument settles interstellar debate
Tue, 29 Jul 2014 22:56:10 EDT - New findings from a NASA-funded instrument have resolved a decades-old puzzle about a fog of low-energy X-rays observed over the entire sky. Thanks to refurbished detectors first flown on a NASA sounding rocket in the 1970s, astronomers have now confirmed the long-held suspicion that much of this glow stems from a region of million-degree interstellar plasma known as the local hot bubble, or LHB.
Weighing the Milky Way: Researchers devise precise method for calculating the mass of galaxies
Tue, 29 Jul 2014 22:49:59 EDT - Does the Milky Way look fat in this picture? Has Andromeda been taking skinny selfies? Using a new, more accurate method for measuring the mass of galaxies, and international group of researchers has shown that the Milky Way has half the Mass of the Andromeda Galaxy.
Research shows impact of soft drinks in meal planning
Tue, 29 Jul 2014 22:49:57 EDT - New research has looked into whether we take liquid calories into account when planning meals. Participants completed a computer-based match-fullness task which assessed the expected satiation of meals that included either a calorific drink, a non-calorific drink, or a snack with the same energy content as the calorific drink. The researchers also explored the contribution of carbonation on expected fullness.
Prehistoric dairy farming at the extremes
Tue, 29 Jul 2014 22:49:55 EDT - Finland's love of milk has been traced back to 2500 BC, thanks to high-tech techniques to analyze residues preserved in fragments of ancient pots.
